If this protocol does not operate as expected, check that another serial
protocol is not using the same COM port.
DNP3 protocol ignores any parity setting in the COM settings group;
DNP3 is defined as an 8 bit/no parity protocol with a 16-bit CRC every 16
bytes. This provides better error detection than parity.
